EPDM rubber remains one of the most widely used elastomers in the industrial market—and for good reason. Known for its durability, weather resistance, and insulating properties, EPDM rubber products are an essential material choice for manufacturers seeking reliability across a wide range of applications.

Qualiform specializes in producing high-performance EPDM rubber parts using both standard and proprietary fiber-reinforced formulations. Each component is molded with precision, designed for function, and built to last—whether the requirement is environmental resistance, thermal stability, or flexibility under pressure.

What Is EPDM Rubber?

EPDM (ethylene propylene diene monomer) is a high-density synthetic rubber designed to perform in extreme conditions. As a non-polar elastomer, it is resistant to moisture, steam, sunlight, ozone, and oxidation—making it a preferred option for outdoor use, electrical insulation, and vibration isolation.
